Asbestosis

Asbestosis is a chronic, progressive lung disease caused by inhaling asbestos fibers. It is characterized by diffuse interstitial fibrosis of the lungs, leading to impaired lung function and restrictive lung disease. Symptoms include shortness of breath, cough, and chest pain, often developing decades after initial exposure.

Use this code for documented cases of asbestosis, typically confirmed by a history of asbestos exposure, characteristic imaging findings (e.g., pleural plaques, interstitial fibrosis on chest X-ray or CT scan), and pulmonary function test abnormalities. This diagnosis is often made by an occupational medicine specialist or pulmonologist.

• Ensure documentation clearly links the lung disease to asbestos exposure.
• Do not confuse with other pneumoconioses; verify the specific causative agent.
• Sequence as the primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity affecting treatment.
